Abstract

An accessory mounting system for a vehicle includes a mirror mounting button attached at an in-cabin surface of the vehicle windshield and a mounting element attached at the in-cabin surface of the windshield separate from the mounting button. An interior rearview mirror assembly has a mirror head and a mirror support, which includes a mirror mount configured to mount the mirror assembly to the mirror mounting button. A module is configured to be received at and supported by the mounting element attached at the windshield. The module accommodates a forward facing camera that views through the windshield. The forward facing camera may be part of a driver assistance system of the vehicle. With the module received by and supported by the mounting element, the mirror mount can be mounted to the mirror mounting button and can be demounted from the mirror mounting button without demounting the module from the mounting element.

First claim

We claim:

1. An accessory mounting system for a vehicle, said accessory mounting system comprising:
a mirror mounting button adhesively attached at an in-cabin surface of a windshield of a vehicle equipped with said accessory mounting system;
a mounting element attached at the in-cabin surface of the vehicle windshield separate from said mirror mounting button;
an interior rearview mirror assembly comprising a mirror head and a mirror support;
wherein said mirror head comprises a mirror reflective element and a mirror casing;
wherein said mirror support comprises a mirror mount that is configured to mount said interior rearview mirror assembly to said mirror mounting button;
a module configured to be received at and be supported by said mounting element attached at the in-cabin surface of the vehicle windshield;
wherein said module accommodates a forward facing camera;
wherein, with said module received by and supported by said mounting element, said forward facing camera views through the vehicle windshield;
wherein said forward facing camera comprises (i) a CMOS image sensor and (ii) a lens;
wherein said forward facing camera comprises part of a driver assistance system of the equipped vehicle;
wherein, with said module received by and supported by said mounting element, said mirror mount can be mounted to said mirror mounting button and can be demounted from said mirror mounting button without demounting said module from said mounting element; and
wherein a light absorbing layer disposed at the vehicle windshield at least partially masks the presence of said mounting element from view by a viewer who is viewing from outside the equipped vehicle through the vehicle windshield.

2. The accessory mounting system of claim 1 , wherein said module accommodates at least one accessory selected from the group consisting of (a) a rain sensor, (b) a light sensor, (c) a tire pressure monitoring system receiver, (d) an antenna, (e) an antenna for an entry system, (f) a component of an electronic toll collection system, (g) an antenna for a global positioning system, (h) a component of a telematic system, (i) a speaker, (j) a microphone, (k) an illumination source, (l) a garage door opener, (m) a compass sensor, (n) a user actuatable input and (o) a display.

3. The accessory mounting system of claim 1 , wherein said forward facing camera provides input for a camera-based “black box” recorder system.

4. The accessory mounting system of claim 1 , wherein a shadeband is disposed at the vehicle windshield at least proximate to where said mounting element and said mirror mounting button are attached at the in-cabin surface of the vehicle windshield.

5. The accessory mounting system of claim 1 , wherein said light absorbing layer disposed at the vehicle windshield at least partially masks the presence of said module from view by a viewer who is viewing from outside the equipped vehicle through the vehicle windshield.

6. The accessory mounting system of claim 1 , comprising a housing that at least substantially hides the presence of said module from view by a person viewing from inside the vehicle cabin.

7. The accessory mounting system of claim 6 , wherein, with said module received by and supported by said mounting element, an uppermost portion of said housing is disposed above said mounting element.

8. The accessory mounting system of claim 1 , wherein said mirror mount makes a breakaway connection to said mirror mounting button.

9. The accessory mounting system of claim 1 , wherein said module accommodates a rain sensor.

10. The accessory mounting system of claim 1 , wherein said driver assistance system comprises at least one of (i) an automatic headlamp control system of the equipped vehicle, (ii) a collision avoidance system of the equipped vehicle, (iii) a windshield fogging detection system of the equipped vehicle and (iv) a rain sensing system of the equipped vehicle.

11. The accessory mounting system of claim 1 , wherein said interior rearview mirror assembly comprises an interior rearview video mirror assembly comprising a transflective electrochromic mirror reflective element and a video display screen.

12. The accessory mounting system of claim 1 , wherein said mirror reflective element comprises a prismatic mirror reflective element and wherein said interior rearview mirror assembly comprises a double-ball prismatic interior rearview mirror assembly.

13. The accessory mounting system of claim 1 , wherein said mounting element is adhesively attached at the in-cabin surface of the vehicle windshield.

14. The accessory mounting system of claim 1 , wherein said mirror reflective element comprises an electrochromic mirror reflective element and wherein said interior rearview mirror assembly comprises a double-ball electrochromic interior rearview mirror assembly.

15. The accessory mounting system of claim 1 , wherein said module accommodates at least one accessory selected from the group comprising (a) a rain sensor and (b) an antenna.

16. The accessory mounting system of claim 1 , wherein said module accommodates electrical circuitry associated with said forward facing camera and wherein said electrical circuitry connects with a communication bus of the equipped vehicle.

17. The accessory mounting system of claim 16 , wherein said communication bus comprises a CAN bus.

18. The accessory mounting system of claim 16 , wherein said communication bus comprises a LIN bus.

19. The accessory mounting system of claim 1 , wherein said CMOS image sensor comprises a multi-pixel photosensor array having at least 250,920 pixels.

20. The accessory mounting system of claim 1 , wherein said camera has a dynamic range greater than about 60 dB.

21. The accessory mounting system of claim 1 , wherein said camera has a dynamic range greater than about 80 dB.

22. The accessory mounting system of claim 1 , wherein said camera has a dark current less than about 0.4 nA/sq. cm.

23. The accessory mounting system of claim 1 , wherein said camera has a dark current less than about 0.2 nA/sq. cm.

24. The accessory mounting system of claim 1 , wherein said camera has a signal to noise ratio greater than about 40 dB.

25. The accessory mounting system of claim 1 , wherein said camera has a signal to noise ratio greater than about 50 dB.

26. The accessory mounting system of claim 1 , wherein said driver assistance system comprises an automatic headlamp control system of the equipped vehicle.

27. The accessory mounting system of claim 1 , wherein said driver assistance system comprises a collision avoidance system of the equipped vehicle.

28. An accessory mounting system for a vehicle, said accessory mounting system comprising:
a mirror mounting button adhesively attached at an in-cabin surface of a windshield of a vehicle equipped with said accessory mounting system;
a mounting element attached at the in-cabin surface of the vehicle windshield separate from said mirror mounting button;
an interior rearview mirror assembly comprising a mirror head and a mirror support;
wherein said mirror head comprises a mirror reflective element and a mirror casing;
